You are a Pega developer working on a large-scale application.

Comprehensive and Detailed Explanation From Exact Extract:

Pega’s configuration management features, as outlined in Pega Academy’sLead System Architect Missionand thePega Certified Lead System Architect Study Guide, provide various options for managing application settings. Application Settings are specifically designed for environment-specific, user-configurable settings that are packaged with the application during migration.

Option A (Incorrect): Configuration Sets are used for managing test configurations in Pega’s testing framework, not for runtime application behavior settings, per theTesting Configurationmodule.

Option B (Incorrect): Dynamic System Settings (DSS) are system-wide settings managed by administrators, not easily configurable by production users. They are not packaged with the application, as noted in theSystem Configurationguidelines.

Option C (Incorrect): Rule System Settings is not a standard Pega feature. The term may confuse with DSS or other rule types, but it does not apply here, per theConfiguration Managementmodule.

Option D (Correct): Application Settings are rule-based, user-configurable settings that can vary by environment (e.g., via ruleset versioning) and are packaged with the application during migration. They are ideal for production user access, as documented in theApplication Settingssection of Pega Community.
